IMPROVEMENT IN TACK-HAMMERS.

Specification forming part of Letters Patent No. 175,322, dated March 28, 1876; application filed February 21, 1876.

To all whom it may concern Be it known that I, WILLIS C. AVERY, of Wallingford, in the county of New Haven and State of Connecticut, have invented an Improvement in Tack-Hammers, of which the following is a specification In the accompanying drawing, Figure 1 represents a top view; Fig. 2, a perspective view, and Fig. 3, an end view of my improved tackhammer. l

Similar letters of reference indicate corresponding parts.

My invention relates to an improved hammer for sticking and driving tacks in a ready manner without necessitating the holding of the tack with the fingers while it receives the blows of the hammer, which is also used for pulling or drawing the tack, without injury to the carpet or tack.

The invention consists of a tack-hammer with wedge-shaped pene end, having a dovetailed groove or recess diminishing in width and depth from the body of the hammer toward the sharp edge of the pene.

In the drawing, A represents the hammer, that is applied in the customary wayby a central eye to the handle B. The hammer has at one end a round head of the usual shape for driving in the tack, and opposite thereto a pene end, B, of wedge-shape, tapering to a sharp edge and extending from the body of the hammer A in the direction of the handle and at a slight outward inclination to the axis of the same. The pene end B is provided with a longitudinal dovetail groove or recess, a, that is of greater depth at the larger end, and diminishes in depth and width toward the edge of the pene end, as shown clearly in Fig. 3. The tack is inserted with its head into the groove or recess and held by the edges of the dovetail for the purpose of being driven in by a light blow at the required place without necessitating the holding of it with the fingers. The pene-end is then detached from the head of the tack and finally driven home into its seat in the floor by the round head of the hammer. The sharp edge of the pene end serves also for the purpose of being pressed under the head of the tack when the same is to be withdrawn, the carpet yielding to allow the recessed edge to pass under the head of the tack. The hammer is then taken hold of firmly at the round head and the handle brought at the same time from the horizontal toward a vertical position, which joint operation pulls or draws the tack from its seat without injury to the carpet or tack.

minishes and tapers toward the sharp or pointed edge, substantially as specified.
